2-stroke or 4-stroke???
Hello,
O.K. you 90's Fun-Fly plane guys... I need your opinions.
I've been working on a Fun-Fly competition plane for a while now and was wondering if a 4-stroke engine could give the same performance as the 2-stroke engine with a pipe. Most of the guys, at that time, were using the latter set-up to power their planes. I'm not looking to compete, but would like the same or better performance. Do you think a 4-stroke would be comparable?... better??... or worse???
The kit suggest a 25-35 size 2-stroke engine with tuned pipe. What would be the 4-stroke engine equalivant?
Thanks,
Phil

RE: 2-stroke or 4-stroke???
Are you working on a stick and boom fun fly plane or a 3D plane? The stick and boom planes that are designed for NCFFA stuff seem to do better with piped 2 strokes. The hovering and harriering planes do well with 4 strokes as well as strong 2 strokes.
